HPC – Structures

Any relatively detailed structural mechanics model – e.g., mesh size in excess of ~500K DOF – is going to take a very long time to solve on a single CPU core. ANSYS HPC reduces the time to solution significantly. For larger models (in excess of ~10 MDOF) parallel processing with ANSYS HPC is needed to make the simulation feasible; a single CPU core typically cannot access enough computer memory to handle these models.

Design Impact

Reducing turnaround time

More design evaluations per day

Simulating larger or more complex models

ANSYS Advantages

Good scalability of distributed solvers up to 128 cores and above.

A large variety of structural analysis problems can benefit from hardware accelerators (i.e. NVIDIA GPUs and Intel Xeon Phi coprocessors). Besides the sparse direct solvers, the PCG iterative solvers are – for example – also supported by GPUs.

Each HPC license can enable either a CPU core or a GPU socket (or coprocessor). This adds a lot of value to HPC in terms of flexibility and speed – i.e., get the highest speedup with whatever combination of CPU cores and hardware accelerators is available.
